PSAT Math Multiple-Choice Practice Question 767

Correct Answer: D

Explanation:

(D) A function intersects the x-axis at its roots, where y = 0: this will occur when any of these three factors equals 0. Set each factor equal to 0 to determine the x-values:
x = 0
x - 5 = 0 so x = 5
x + 2 = 0 so x = - 2
Therefore, the three x-values are 0, 5, and -2, which is choice (D).
